What is decanter centrifuge?
Introduction:
A decanter centrifuge is a kind of continuous operation sedimentation centrifuge.It mainly consists of a cylindrical conical drum, a screw conveyor, a drive system, a feeding system, and a discharge system. The drum rotates at a high speed, and the screw conveyor rotates at a slightly different speed inside the drum.
Working Principle:
The material to be separated is fed into the drum through the feeding system. Under the action of centrifugal force, the solid particles in the material are thrown to the inner wall of the drum and form a sediment layer. The screw conveyor continuously transports the sediment to the conical end of the drum for discharge. The liquid phase, on the other hand, flows out from the other end of the drum, thus achieving the separation of solid and liquid phases.
Applications
Wastewater treatment: It is widely used in municipal and industrial wastewater treatment plants to separate suspended solids from the wastewater, helping to purify the water and meet the discharge standards.
Food processing: In the food industry, it is used for separating and dewatering various food materials, such as separating starch from potato slurry, or dewatering fruits and vegetables.
Pharmaceutical industry: It is used in the production process of drugs to separate and purify solid liquid mixtures, such as separating crystals from the reaction solution.
Mining and mineral processing: In the mining industry, it is used to separate and recover valuable minerals from the ore slurry, or to dewater the tailings.

Separation principle
Sedimentation horizontal decanter centrifuge: It mainly relies on the action of the centrifugal force field to make the solid particles in the suspension settle on the wall of the drum, thus achieving solid liquid separation. It is commonly used for the separation of suspensions in fields such as sewage treatment, chemical engineering, and pharmaceuticals, for example, the dehydration treatment of sludge in urban sewage treatment plants.
Filtration horizontal decanter centrifuge: There is a screen on the drum wall. Under the action of centrifugal force, the liquid is discharged through the screen, and the solid particles are retained on the screen, thereby realizing solid liquid separation. It is suitable for the separation of suspensions with relatively coarse solid phase particle sizes and high concentrations. For instance, it is used for the dehydration of concentrates in some mining concentrators.
Innovation technology
Efficient Liquid Discharge: The centripetal pump structure can generate a powerful suction force, enabling the rapid discharge of the separated liquid from the drum. This helps to improve the separation efficiency of the centrifuge, shorten the time of a single separation cycle, and thus enhance the overall processing capacity.
Reduction of Turbulence: The centripetal pump structure can make the liquid flow out more smoothly during the discharging process, reducing the turbulence and disturbance of the liquid. This is beneficial for improving the separation effect, as turbulence may cause the settled solid particles to resuspend, affecting the purity of solid-liquid separation. When processing materials with high requirements for separation precision, such as the separation of biological agents in the pharmaceutical industry, it can effectively ensure the separation quality.
Wear Reduction: This structure can reduce the erosion and wear of the liquid on components such as the drum and the screw conveyor. Since the liquid is discharged more smoothly, it reduces the direct impact of high-speed liquid on the inner wall of the equipment, thereby prolonging the service life of the equipment, reducing maintenance costs, and minimizing downtime.
Full range of models to meet diverse needs
Phase decanter centrifuge: Three-phase decanter centrifuge: It is a kind of horizontal decanter centrifuge equipment used to achieve the separation of liquid-liquid-solid three phases. In this centrifuge, through the centrifugal force field generated by high-speed rotation, substances in three different phases (two immiscible liquids and one solid) are separated according to the density differences.
One liquid phase (such as the light liquid phase with a lower density) will gather in the inner layer of the drum, and the other liquid phase (the heavy liquid phase with a higher density) will be in the outer layer of the drum, while the solid particles will settle on the inner wall of the drum. Then, through the corresponding discharge devices, the three-phase substances are respectively discharged from the centrifuge to achieve the purpose of separation.
Three-phase decanter centrifuges are widely used in the process operations involving liquid-liquid-solid three-phase separation in industries such as petrochemicals, food processing, and sewage treatment.
Phase decanter centrifuge
Two-phase decanter centrifuge: It is a kind of horizontal decanter centrifuge equipment mainly used to achieve the separation of solid-liquid two phases or two immiscible liquid-liquid two phases. When carrying out solid-liquid separation, through the powerful centrifugal force field generated by the high-speed rotation of the centrifuge, the solid particles settle on the inner wall of the drum, while the liquid is distributed inside the drum.
Then, the screw conveyor is used to push the settled solids to one end of the drum for discharge, and at the same time, the liquid flows out through a specific liquid discharge port, thus completing the solid-liquid separation. When carrying out liquid-liquid two-phase separation, two immiscible liquids with different densities are stratified according to the density difference under the action of centrifugal force. The liquid with a higher density is close to the outer wall of the drum, and the liquid with a lower density is close to the center of the drum. Then, they are respectively discharged through the corresponding liquid discharge ports to achieve liquid-liquid separation.
Two-phase decanter centrifuges are widely used in many fields such as chemical industry, pharmaceuticals, environmental protection, and food industry for the separation of various suspensions and emulsions.
